1. Biomarkers for Better Understanding of the Pathophysiology and Treatment of Chronic Pain : Investigations of Human Biofluids
Sammanfattning : Chronic pain affects 20 % of the global population, causes suffering, is difficult to treat, and constitutes a large economic burden for society. So far, the characterization of molecular mechanisms of chronic pain-like behaviors in animal models has not translated into effective treatments. LÄS MER
2. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations
Sammanfattning : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. LÄS MER
3. Laboratory Investigations of Frost Action Mechanisms in Soils
Sammanfattning : Phase change of the water in the soil skeleton under cold climate conditions (also known as frost action in soils) affects soil properties and can be responsible for serious alterations in a soil body; causing damages (due to the volumetric expansion known as frost heave) to structures on or below the ground surface such as foundations, roads, railways, retaining walls and pipelines, etc. In order to improve the current design methods for roads against frost action, the Swedish Transport Administration (Trafikverket) has initiated a research program.

4. The Use of Laboratory Analyses in Sweden : Quality and Cost-Effectiveness in Test Utilization
Sammanfattning : Laboratory analyses, essential in screening, diagnosis, treatment, and monitoring of disease, are indispensable in health care, but appropriate utilization is intricate. The overall aim of this thesis was to study the use of laboratory tests in Sweden with the objective to evaluate and optimize test utilization. LÄS MER
5. Mass Stabilization, Stability and Settlement in Mass Stabilized Peat
Sammanfattning : Peat is badly suited as a base for road and railway embankments due to its geotechnical properties. The usual procedure has been, therefore, to excavate peat and replace it with blasted rock. LÄS MER
